thanks again Kevin. If I wasn't I so old I'd just come wash parts for you. I have been building pan"s and shovels since the 70/80/s and I have learned more from you in the last few years than ever. Thank YOU. I'd love to buy you a drink.
thank you so much chuck. i love pans and shovels too. great engines. like these, they had issues come and go too but for the most part, with diligence, they can run forever! Long Live Pans, Shovels, and Evos! LOL
I watch these videos, and think “I could do that!”, then I look at the pile of broken stuff in my garage that I’m going to fix ‘one day’ and realize, I’m an idiot! Great to watch a true professional work!!! 👍
Thanks Bill!
You’re not the only one. I know a guy that constantly gets himself into trouble in that his ambitions are beyond his capabilities 😊

Pick one project and finish it.
These tear down videos are some of my favorite, on the Tube and from Kevin. This gentleman has such a wealth of knowledge, and it is truly a privilege to be able to watch and listen when he speaks in detail about what he sees and why it may be while he’s tearing down or what he does when he’s building. Thank you man!
The relationship between human and machine is a special one.
thank you so much for the kind words and support.
keep em coming, Kevin.
Just found this series. Just up my alley for sure. Fixing anything broken is the easy part. Why it broke is the real deal to ensure your not wasting money on a bad road back to the shop.
Please keep doing these tear down videos! Love them. I subscribe to "I Do Cars" also and his channel is strictly automotive engine teardowns. He disassembles the failed engines to see what happened/caused the failure. Fascinating stuff and this is the Harley version!👍
Enjoyed that Kevin, thank you. I've been a mechanic (mostly HVAC) my entire life, I can always spot someone good by their attitude and willingness to share knowledge.
I just recently found you here. I recently bought a 09 twin cam. Going to be doing cams this spring. Totally redid the primary last spring. Love your wealth of knowledge. Hopefully I don’t find too much nasty. Definitely giving me things to look for.
great video as usual like the one a day video idea thanks for taking the time to make them
youre welcome. thank you for support!
ALRIGHT! Finally something good to watch today, I was getting a little worried. Thanks Kevin.
Thank you so much Sir!!! I appreciate you and your support.
Awesome as always!
Thanks Raider!
Another great video
Really enjoyed this tear down vid. I too have a 110 that the lifters failed and I have 7-8/1000s runout. Breaks my heart but at least watching these show me what exactly the shop I use was talking about.
You must be so disappointed in the quality of your motorcycle. You thought you were going to get a great motorcycle you spent a fortune on a Harley-Davidson and it took a dump. I just can't believe how the quality of a Harley-Davidson has deteriorated in the last 20-plus years after the demise of the Evolution motor. I hear from another RUclipsr that there is kits out there where you could put an Evolution motor in a twin cam frame. It might be something to consider.
Kevin, enjoyed the video. Didn't make the premeire, been under the weather for a few days, slowly starting to feel better. Thanks for the video.
Hope you feel better soon sir. Thank you !
Great video thank you
Great job showing and telling, keep up the good work take care and have a great day see ya on the next video see ya bye.
Thank you Kevin for making a video on my engine!!!
Youre welcome sir! Thanks for answering in the comments. I will tell the story in tonights M8 video. Hated to miss the live chat...i was driving out of state on a biz trip overnighter.
May have to miss the premiere, on account of the weather’s spoda be eminently rideable tomorrow. Gotta seize these last few days while I can.
We always tore down our engine's and washed everything ! Dried and wrapped everything in newspaper and boxed . Then brought to to get rebuilt ! Saves time and money.. Greetings from Asheville NC .
Thanks as always good stuff,,,
thank you Paul
Dude, you are a genius. I'm in Winder and the next warm workday I would like to swing by and ask a question or two about my 2001 Heritage Softail. Your opinion would really mean a lot. Love the videos, by the way.
Thanks!
WOW!!!! a63strat THANK YOU SO MUCH! Very kind and generous of you.
Thank u for explaining crank rod play ... just ran across that ..
youre welcome. thanks!
Good video, always interesting stuff and you don't know what you might find.
surprises aren't always good things. but to the owner....he said "im glad i did this now, i was going to be doing it anyway once things failed or got worse". Thank you sir.
Another great video, thanks! One thing I'm very interested in is the cost for these rebuilds. Would you ever consider doing a price reveal on some of them?
Each are different really and can vary broadly depending on 5 things as I have found over the years... current condition of bike, how it will be used, riding style, desired power output, and confidence level of all associated stock components. That determines the required budget and everyone's answers are different to these questions.
Good show Kevin.
Thank you Jerry.
Can’t wait for working on the M8. 🏍💨🏍💨
Thank you sir. just dropped tonight!
As someone that has a 110 screaming eagle tire shredder kit on my 2011 dyna this is a bit concerning though I don't beat on it all that much honestly 🤔
When my twin cam went out the tech Rodney @ LCHD said the factory says up .006 runout on the crank is ok my crank had .087 and was easily visible to the naked eye lol stock oil pump quit working while I was on the interstate motor was not happy lmao
I can't understand how an engine on such an expensive motorcycle and really expensive in the case of a CBO has catastrophic engine failure and 20 something thousand miles. Mine 20 plus year old Harley Sportster 883 has almost 400,000 miles on the original engine. But just like the Evolution Big twin the Evolution Sportster is discontinued as well. The only time I split the cases on my 1965 Triumph TR6 was because it was 40 years old and the camshaft we're both worn out.
HD is not making quality products for years. They have to change to liquid cooling to get the temperatures down.
HD stands for high dollar and keep coming back for more parts even if bike was brought new. 😁
The price you pay for beauty man!! Does a 20 yr old gf cook everday and clean the house to perfect... no .. we know what we are getting when we buy Milwaukee 😏
If we wanted a bike that ran forever wo issues we would buy honda.. ahhh come on!!!!
What's they're not telling you?
Is all of the hot roding people due to make them break I see guys beat on them constantly.
Boy that guy works fast
I missed seeing a destroyed cam plate, they already removed ?
Hey Kev have a 2009 CVO Ultra with a total engine rebuilt right from crank shaft, Screaming eagle cam plate, piston jets everything in the year 2016 sounds great but the past worries, is it reliable now, miles after rebuild around 10k.
Kevin, what causes the piston slap, the cylinders not machined correctly? I bought a 100 CI S&S big bore kit, they sent the shop doing the work 8 sets of cylinders before there were 2 that would fit. It has piston slap until it warms up,. Is this normal for a big bore set up or do you think there is an issue?
What do you have on the 110 screamin eagle counter balance chain tensioner shoes I a 2017 flss lifters went out a 42000 miles got lucky on that now I am wondering when the counter balance shoes go out out can't find any info on how long they last I don't hot rod the bike have 43000 miles on it now?
The 110s had more valve spring tension. This may cause problems.
Are special tools required to split cases and reassemble
What would you charge to do a 107 s&s thank you
I got a 2003 88 that needs some work if you want to tear is down and do some upgrades lol.
Kevin, your videos are depressing when it comes to the "newer" Harley engines. Sorry, but I'll never give up on my EVO.
The lifters always tell you they're gonna give up right? Always a tapping right?
Hi Kevin, I had a severe sumping issue on my M8 and the motor eventually blew with a piston rotating in the cylinder. Do you think the extreme overheating could of caused the piston rings and cylinders to be compromised to the point the piston could turn in the cylinder destroying my heads and motor?
it takes a lot to spin a piston....a lot! typically only happens with a dropped valve or broken skirt. wow. heat can destroy an engine....a lot of heat really could.
Even thou I have no mechanical ability I do enjoy the channel. Does your shop work on metric bikes?
Thank you so much Jerry. im glad you enjoy it! No sir we dont...i prefer to focus on our specialty.
Is the crank in that shape because Harley started using pressed bearings instead of staying with the the timken bearings during assembly to cut cost? I have a 103ci HO engine but upgraded to a stage III 110ci kit; apparently if I want to go up to a 117ci I'd have get a new crank to handle the HP and TQ.
not really. a tapered main bearing vs roller bearing really doesnt contribute to scissoring or twisting a crank. you dont have to have a brand new crank, but i would certainly reman and work your stock one at least.
I love the tear down videos. Seems like the 110's were problematic. Good video Kevin. Thanks.
thank you sir. not all were but they did have some issues.
@@KevinBaxter do you feel like the roller lifter bases are at fault a lot. ??
I replaced the lifters on my 110 cvo at aprox. 40000 kilometers to prevent exactly this. I was advised to do so by one of the mechanics at the shop where i bought the bike. He told me he had a catastrophic engine failure caused by a lifter exploding while running the bike on a dyno. He told me this is a known problem wich can ocure on 110 cvo engines. Seeing this video i'm glad i did. Changed the cam plate, cam bearings for a SE camplate en bigger oil pump in the proces. Bike stil runs like a dream. 😊
Do you still own thr bike? If so what is the milage now? Any problems since then?
Just thinking to buy one abt 80 k km. Not sure if its a gamble
I still own the bike and it has 60000 km's on it now. I noticed that on several of the failures on 110 engine the lifters were the cause of the problem. If the bike you are interseted in runs good you could considder purchasing it and upgrade it with new lifters.
@@kaantuncer7884look at the comment above
anybody ever do a study or count of the damage harley engines per lets say 1000 produced. also what % of damage engines is higher, complete factory stock or upgraded engines with preformance parts. tks. keep em coming.
I never liked stainless steel fasteners. They will gall easily and inherently have less tensile strength than a good high carbon steel fastener. But customers would insist on them anyway.
Please. What do you use for bore and stroke on YOUR 117 cu in engine?
4 3/8 stroke with 4 1/8 bore.
I could hear bearing noise when you rolled the crank over
An evo tear down and case swap would be cool as hell.. just sayin my man…
That just so happens to be my plan exactly my friend ... i just so happen to have one with a brand new polished case right behind that tear down table next in line ;)
35 years of trouble free honda and yamaha........3 years with my first harley and i'm still stunned as to what a pos it is. first and last.....that engine has no miles on it..what a shame
Had a 2010 CVO 110. Worst HD engine I’ve ever had. Bike was babied and that 110 used one quart of oil every 1,000 miles.
ouch. hate to hear that.
👍👍👍👍👍
dialelectric grease or never-seize?
he had used both appropriately.
The sumping caused the big end bearings to fail?
indirectly possibly so. excessive heat would be a factor.
@@KevinBaxterI find the entire sumping issue fascinating. Chicken or egg question stacked 2 or 3 levels deep to discover the cause and effect of other issues.
Skunk Works indeed. 👍
Any way to diagnose a 110s condition by the sound?...LOL. Mine is a 2016 from a CVO Limited. Had the lifters replaced early in it's life. It has 42k on it and runs well and well kept. Maybe it is just time for the complete rebuild to a 117! :)
I have learned to identify noises over the years and most of the time can nail it pretty well....but...i still get surprised. not only by where a noise can originate, to where its heard. but also....how something can be a bad issue inside yet NOT make a noise. engines are fickle things.
Mine went 117 13k miles ago at 60k.
@@KevinBaxter update on my 110. Had the cam, lifters replaced. Looks like I caught it in time. No damage to anything else. Cylinders fine, run-out was in spec.
👍👍
It’s a Frankenstein motor!
Great video, how many miles are on this engine? I have a 110 water head with 54,000 on it, just wondering
Thomas my engine had 22,369 miles on it. Always changed oil in all holes at 4,000 miles. I have never had the engine above 5,000 rpm
Thomas my engine had 22,369 miles on it. Changed oil every 4,000 miles always used Amsoil. I have never had the engine above 5,000 rpm, mostly up only around 3,800 rpm
Would. 96. Run to. Hot if turn it in to. 110. Are. Put. W. Are e. Oil. Cooler. On it.
I'm starting to regret my HD purchace.
Please dont. Remember...there are hundreds of thousands of bikes out there. We are specialists at solving and improving complex issues and we represent a very small number of all those out there. My goal is to explain issues in case you do have one and help you understand what it takes to fix them.
@@KevinBaxter Here in Ontario there isn't many riders of any brands tbh. I forget how many there in the U.S. I raced at Pittrace a number of times this summer and see so many HD's on the way there. I still love my HD and your channel. I learn new things all the time!
Job security motors
Boy, 40,000 miles. Customer sure can't be happy with that.
i actually mis-spoke. it was 24,000 miles.
24,000 miles!!??? 🤣🤣🤣🤣🤣🤣🤣🤣🏍🏍 buy a better bike !!!!! But if you have to be one of the " BRO'S" your hands are tied !!
Did I miss how many miles were on this engine, or do you even know?
man that sux for that individual...
yes sir.
These teardown videos just affirm the those chrome air compressors are really crappy !!! 🤮🤮🤮🤮🤮🤮
When I get. Mile on my bike. I want. Build it. Take 96. Make 110. With gear cam. And do the heads and. Get kit IL let you. Choice. The best. I want you to. Do it if was your bike.
🚶💭 👍👍👍👍👍+ ☕
Case failure
Talk fast to
Kevin, is it fair to say that just about every engine you see has sumping issues? Seems like HD is putting out some sub par motors. My 2018 107 most likely has this issue too.
Thanks
By the time they get to me, yes...many do but not all. It's easy enough to detect and check.
I have a 2020 m8 107 motor and it has 50k miles and runs great still
@@adminadmin9997 From 2020 and up, didn’t they finally get it right at the Mother Company in regards to the oil pump? From what I understand from an old-timer industry insider, they had upwards of 15 different iterations of the pump although part numbers showed less than that quantity.
